Abstract: To manufacture a sprue-bush which is capable of suitably cooling a melt raw resin in a raw resin-flow path as a whole, there is provided a method for manufacturing a sprue-bush, wherein a shaped part is located on a base part to manufacture the sprue-bush, the base part comprising a raw resin-flow path and a cooling medium-flow path, wherein, in the shaped part, a downstream raw resin-flow path portion is located and a downstream cooling medium-flow path portion is also located, the downstream raw resin-flow path portion corresponding to a downstream side region of a raw resin-flow path of the sprue-bush, the downstream cooling medium-flow path portion being positioned around the downstream raw resin-flow path portion and corresponding to a downstream side region of a cooling medium-flow path of the sprue-bush, and wherein the downstream cooling medium-flow path portion is located to surround the downstream raw resin-flow path portion.

Abstract: An information recording device including a controller records information in a write-once optical disk group including one or a plurality of write-once optical disks. When recording new data, the controller calculates a residual quantity of an alternate area. The calculation of the residual quantity of the alternate area corresponds to a subtraction of a first consumption size and a second consumption size from a size of the alternate area of the write-once optical disk group. The first consumption size is a size of the alternate area already consumed when the data recorded in the write-once optical disk group was erased. The second consumption size is an estimated size of the alternate area to be consumed when the data recorded in the write-once optical disk group is erased. The controller records the new data when the residual quantity is greater than or equal to a third consumption size.

Abstract: In order to provide a sprue-bush which is capable of suitably cooling a melt raw resin in a raw resin-flow path as a whole, there is provided a sprue-bush, comprising a raw resin-flow path and a cooling medium-flow path located around the raw resin-flow path, wherein a width dimension of the raw-resin flow path gradually becomes larger toward a downstream side-end surface of the sprue-bush, and wherein the downstream side-end surface of the sprue-bush is a heat transfer surface.
